3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18          note (in this implementation of the sampler its simply hard routed to
19          the 1st effect send of the sampler channel, no matter what the actual
20          effect type is)
21        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22          note (in this implementation of the sampler its simply hard routed to
23          the 2nd effect send of the sampler channel, no matter what the actual
24          effect type is)
25        - implemented support for internal LADSPA effects
26        - raised limit of program change queue from 100 to 512
27          (as suggested by Alex Stone)
28    
29      * Gigasampler format engine:
30        - implemented the "round robin keyboard" dimension
31        - fixed round robin and random dimensions for cases when number of
32          dimension zones is not a power of two
33        - made round robin use a counter for each region instead of each
34          key
35    
36      * SFZ format engine:
37        - Initial implementation (not usable yet)
38        - added support for v2 multiple stage envelope generators
39        - added a fine-tuned v1 envelope generator instead of using the
40          one from the gig engine
41        - fixed memory leak and memory handling errors
42        - added support for trigger=first, trigger=legato and sw_previous
43        - allow non-numerical key values ("C#4" for example)
44        - "key" opcode now sets pitch_keycenter too
45        - fixed error when unloading instrument with same sample used by
46          multiple regions
47        - added some opcode aliases, like loopmode for loop_mode, to be
48          more compatible
49        - added support for trigger=release and rt_decay
50        - added support for off_mode=normal
51        - added support for random, seq_position, seq_length and volume
52        - added v1 LFO opcodes to parser (no support in engine yet)
53        - added support for amp_veltrack and amp_velcurve_N
54        - fine-tuned the default velocity curve
55        - added support for transpose
56        - fixed crash when using sw_down/up
57        - improved logic for sw_lokey/hikey/up/down/last
58        - added more v1 aliases to parser
59        - reduced memory usage for sfz data
60        - RT-safeness: avoid malloc in audio thread
61        - fixed a bug that could cause voice stealing to fail
62        - optimized sample lookup
63        - improved support for exclusive groups (group, off_by and
64          off_mode)
65        - added support for controller triggered regions (on_locc/on_hicc)
66        - added support for loop_mode=one_shot
67        - fixed playback of 16 bit wav files on big endian CPUs
68        - added support for Ogg Vorbis sample files
69    
70      * SoundFont format engine:
71        - Initial implementation (not usable yet)
72        - RT-safeness: avoid malloc in audio thread
73        - fixed a bug that could cause voice stealing to fail
74    
75      * Host plugins:
76        - AU bugfix: failed to destroy its audio/MIDI devices
77        - Listen to all interfaces on Mac OS X (INADDR_ANY)
78        - VST bugfix: If the host called resume() before and after
79          changing sample rate or block size, the number of channels was
80          incorrectly set to two. This caused silence in Cubase 5.
81        - save engine type (gig, sfz or sf2) in plugin state
82        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
83          64 bit Windows
84    
85      * MIDI driver:
86        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
87          the ALSA sequencer client name
88        - removed limit of maximum amount of MIDI ports per MIDI device, since
89          there is no reason for this limit
90    
91      * LSCP server:
92        - added support for sending MIDI CC messages via LSCP command
93          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

105          "GET EFFECT_INSTANCE_INPUT_CONTROL INFO <effect-instance> <input-control>"
106        - added LSCP command "SET EFFECT_INSTANCE_INPUT_CONTROL VALUE
107          <effect-instance> <input-control> <value>"
108        - added LSCP command "GET SEND_EFFECT_CHAINS <audio-device>"
109        - added LSCP command "LIST SEND_EFFECT_CHAINS <audio-device>"
110        - added LSCP command "ADD SEND_EFFECT_CHAIN <audio-device>"

113        - added LSCP command
114          "GET SEND_EFFECT_CHAIN INFO <audio-device> <effect-chain>"
115        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
116          <effect-chain> <effect-instance>"
117        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
118          <effect-chain> <effect-chain-pos> <effect-instance>"
119        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
120          <effect-chain> <chain-pos>"
121        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
122          <fx_send_id> <effect_chain> <chain_pos>"
123        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
124    
125      * Bug fixes:
126        - Fixed crash which may occur when MIDI key + transpose is out of range
127        - minor valgrind fixes
128        - fixed crash which occured when changing an already deployed sampler
129          channel to a different engine type
130        - fixed crash when deleting a sampler channel or changing engine
131          type while an instrument load was in progress
132        - bugfix: playing a note while changing the instrument could cause
133          a crash, or give "Handing back unknown region" error messages
134        - bugfix: calling SET VOICES (which Fantasia does on start and
135          refresh) could cause instruments to be unloaded
136    
137    Version 1.0.0 (31 July 2009)
138    
139      * packaging changes:
140        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
141          causing e.g. the libgig test to fail when
142          "./configure --disable-jack-driver" was used
143          (patch by Alexis Ballier)
144        - fixed compilation with gcc 4.3
145        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
146        - fixed configure so it detects x86_64 (#107)
147        - fixes for building with newer MinGW versions
148        - fix for building with bison 2.4 (#111)
149        - fixed building with libgig installed in a non-standard directory
150        - minor fix in configure for mmsystem.h detection on MinGW
151        - Windows: look for editor plugins and Fantasia using base
152          directory of liblinuxsampler dll (look in the same directory and one
153          directory above)
154        - configure script fix: removed unconditional use of SSE
155        - fixed building with sqlite installed in a non-standard directory
156        - when cross-compiling, don't try to create instruments.db
157        - fix for new mingw-w64 version, which has usleep
158    
159      * general changes:
160        - bugfix: on some POSIX systems instrument editor plugins refused to
161          load as we used a non-portable Linux specific struct field
162          (fixes bug #70, patch by Ronald Baljeu)
163        - fixed endless loop which occured when loading an instrument editor
164          plugin DLL on Windows systems failed
165        - fixed memory leaks that occurred when liblinuxsampler was unloaded
166        - optimized the SynchronizedConfig class so it doesn't wait
167          unnecessarily long after an update
168        - added support for notifying instrument editors on note-on / note-off
169          events (e.g. to highlight the pressed keys on the virtual keyboard
170          of gigedit)
171        - added support for triggering notes by instrument editors (see above)
172        - be verbose on DLL load errors (on Linux)
173        - fixed di-harmonic triangle LFO implementation (this LFO implementation
174          is only used by very few systems, most pick the int math
175          implementation, which is usually faster)
176        - fixes for audio drivers with varying buffer sizes
177        - experimental support for running LinuxSampler as a DSSI, LV2 and
178          VST plugin
179        - notification events for stream/voice count statistics are now sent
180          only when there are actual changes
181        - added memory ordering constraints to improve stability on
182          multi-core and multi-cpu systems
183        - maximum voices and disk streams can now be altered at runtime
184        - fixed CPU feature detection on x86_64 (maybe fixes #108)
185        - automatic stacktrace mechanism is now turned off by default and can
186          be switched on by command line option "--stacktrace" (the automatic
187          stacktrace mechanism seems to be broken on most systems at the moment)
188        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
189          a pointer to the launched InstrumentEditor object
190        - added optional 3rd party user data parameter for following
191          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
192          InstrumentEditor::Launch(),
193          InstrumentManager::LaunchInstrumentEditor()
194        - theoretical fix: made SynchronizedConfig follow C++0x memory
195          model more strictly
196        - fixes for using large audio device buffers
197        - Windows: add the installation directory to the DLL search path
198          when loading an editor plugin (solves problems with VST and
199          gigedit on systems with other GTK versions installed)
200    
201      * audio driver:
202        - removed the nonsense audio channel constraint (which was hard coded to
203          max. 100 audio channels) for most audio drivers
204        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
205          opposed to the LSCP specs
206        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
207          reflected the wrong value
208        - fixed a memory management bug in ASIO driver
209        - Makefile fix: JACK_CFLAGS wasn't used
210        - JACK: use jack_client_open instead of the deprecated
211          jack_client_new
212        - added (experimental) CoreAudio driver
213        - applied old fixes to the ASIO driver that were included in the
214          previous binary release but accidentally never committed to CVS
215          (fixes #117)
216        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
217          win64)
218        - VST: added support for sample rate and buffer size changes
219        - VST: close editor (Fantasia) when the VST is removed
220        - VST: avoid opening Fantasia more than once for each VST instance
221        - VST: export main function as "main" on Linux too (fix for
222          energyXT)
223        - VST: changed number of output channels from one stereo to 16
224          stereo
225        - added channel routing, fxsends and midi maps to the settings
226          stored in the plugin state
227        - performance optimization of AudioChannel::MixTo() and
228          AudioChannel::CopyTo() methods using GCC vector exensions
229          (if available)
230        - ASIO fixes: avoid initializing the device twice, avoid throwing
231          exception when getting parameters from a disconnected device
232    
233      * MIDI driver:
234        - added JACK MIDI driver
235        - dispatch bank select as ordinary CC as well, the user might seriously
236          want to (mis)use it for some purpose ("fixed" in all current MIDI
237          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
238        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
239          CoreMidi or AU
240        - fixed mingw-w64 compilation error in MME driver
241        - made program change handling in MIDI thread real-time safe by
242          moving the logic to a non-RT thread
243        - fixed minor memory leak in ALSA driver
244    
245      * instruments database:
246        - avoid time consuming samples scanning when adding instruments
247          to the instruments database
248        - added support for handling lost files in the instruments database
249        - Implemented option for adding instruments in separate directories
250          in the instruments database
251          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
252        - work-around for missing fnmatch function on Windows to make
253          instrument database compilable
254        - added instrument database support on Windows
255          works with both standalone mode and VST plugin.
256          the instruments DB file is located in
257          %USERPROFILE%\.linuxsampler\instruments.db which allows different
258          databases for each windows user
259          if no DB is present it automatically creates the .linuxsampler subdir
260          and then creates an empty DB
261        - fixed recursive import, which was broken on Windows
262    
263      * Gigasampler format engine:
264        - fixed a memory leak that could happen when a channel was deleted
265          while notes were playing
266        - made it possible to load an instrument even if the audio thread
267          isn't running
268        - added partial support for the "Controller Triggered" MIDI rule,
269          enough for piano gigs with pedal noise samples
270        - minor fix: only mark FX sends as being modified if really the
271          respective FX send MIDI controller was used
272        - added support for GM global device volume SysEx message
273          (can be selected at compile time to either apply globally to the
274          whole sampler [default] or only to the sampler channels that are
275          connected to the respective MIDI input port the SysEx message arrived
276          on)
277        - bugfix: notes triggered at position 0 in the audio buffer were
278          sometimes wrongly killed in the same buffer, causing no sound to
279          be played
280        - added support for chromatic / drumkit mode Roland GS Sysex message
281          which is usally used to switch a part between chromatic sounds and
282          drumkit sounds (as opposed to their common default setting of MIDI
283          part 10 being a drumkit part and all other ones chromatic parts), in
284          LS however one can switch between the first 16 MIDI instrument maps
285          defined for the sampler
286        - made it possible to create multiple sample channels even if the
287          audio thread isn't running
288        - fixed crash when removing channel with active voices (#116)
289        - bugfix: on sample reference changes (instrument editor), only
290          un-cache the respective sample if it's really not used by any
291          sampler engine anymore
292        - re-cache samples in case they were changed by an instrument editor,
293          e.g. when a sample was added while playing (#82)
294        - fixed hanging notes which occured when note-off event had the exact
295          same time stamp as the voice's note-on event and occured both in the
296          same audio fragment cycle (fixes bug #112)
297        - added support for the "fine tune" and "pitch bend range"
298          instrument-level gig parameters
299        - fixed minor artifacts in pitch bend handling
300        - added support for GS Reset SysEx message
301        - allow gig files to use unlimited downward pitch shifting
302        - added a limit check for upward pitch shifting
303        - bugfix: sometimes, when playing a note twice fast, the second
304          note was silent
305        - fixed crash happening when a pitch bend event arrived at the
306          same time a new instrument was loading
307    
308      * LSCP server:
309        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
310          react on MIDI data arriving on certain sampler channels (so far only
311          Note-On and Note-Off events are sent via this LSCP event)
312        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
313          react on MIDI data arriving on certain MIDI input devices (so far only
314          Note-On and Note-Off events are sent via this LSCP event)
315        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
316          SET DB_INSTRUMENT FILE_PATH
317        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
318          frontends to send MIDI messages to specific sampler channel
319        - added two additional fields to GET FILE INSTRUMENT INFO command -
320          KEY_BINDINGS and KEYSWITCH_BINDINGS
321        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
322          was incorrect
323        - Optimized the retrieval of the MIDI instrument mappings
324        - added new LSCP command "SET VOICES" to globally alter the maximum
325          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
326          be triggered respectively
327        - added new LSCP command "SET STREAMS" to globally alter the maximum
328          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
329          which will be triggered respectively
330        - bugfix: retry if "select" returns EINTR (this fixes a crash when
331          a gigedit file dialog is opened)
332        - close all connections when LSCPServer is deleted
333        - hard close of all sockets on exit
334        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
335          driver
336    
337      * Bug fixes:
338        - fixed a crash which occurs when removing a sampler channel waiting
339          to start instrument loading after another channel
340        - fixed a crash which occurs when removing a sampler channel with
341          instrument loading in progress (bug #113)
342        - fixed termination caused by uncaught exception when adding MIDI
343          instrument with PERSISTENT load mode
344        - fixed possible iterator invalidations when resetting the sampler
345        - fixed memory leaks when issuing the following LSCP commands:
346          GET AUDIO_OUTPUT_DRIVER INFO
347          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
348          GET MIDI_INPUT_DRIVER INFO
349          GET MIDI_INPUT_DRIVER_PARAMETER INFO
350        - fixed possible compilation error when sqlite is not present
351        - fixed orphaned pointers when setting maximum voices limit (bug #118)
352        - fixed crash when changing the audio output device of a sampler
353          channel with loaded instrument and start playing notes
354        - fixed endless loop in Engine::SuspendAll() (bug #120)
355        - fixed a low-level atomic load function that was broken on 64-bit
356          PowerPC, which probably could cause crashes on that platform
357        - fixed a memory management error which could cause a crash when a
358          plugin was unloaded
359        - bugfix: two private structs had the same name, which could cause
360          problems if the linker chose the wrong constructor
361        - fixed low-level ConditionServer usage bug that caused lockups on
362          Windows
363    
364    
365    Version 0.5.1 (6 December 2007)
366    
367      * packaging changes:
368        - added autoconf checks for pthread library
369        - added autoconf check for pthread bug found on certain NPTL-enabled
370          glibc versions (see Gentoo bug report #194076)
371        - added autoconf checks for MS Windows
372    
373      * general changes:
374        - bugfix: the thread used by an editor plugin didn't die when the
375          editor closed
376        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
377          out all the space. operator--() did not apply size_mask after
378          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
379          order to avoid problems with the _NonVolatileReader functions.
380        - bugfix: Stream.h: added a missing divide by BytesPerSample in
381          GetWriteSpace(). Since this function is currently only used in
382          the stream's qsort() compare function, it didn't trigger any
383          bugs.
384        - Resampler.h, Synthesizer.h: cubic interpolation now works in
385          24bit mode too. Faster method to read 24bit words on little
386          endian machines (x86): replaced 3 byte reads + shifts with a 1
387          unaligned 32bit read and shift
388        - experimental support for MS Windows (MIDI input via MME, AUDIO
389          output via ASIO)
390        - made handling of SIGINT signal (Ctrl-C) a bit more robust
391        - support for monitoring the total number of active disk streams
392          (new LSCP commands: GET TOTAL_STREAM_COUNT,
393          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)

400    
401      * LSCP server:
402        - added support for Windows style path / filenames, however with
403          forward slash path separators instead of backslash
404          (i.e. "C:/foo/bar.gig")
405        - allow naughty liblscp to send non-string device parameters within
406          apostrophes as well
407        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
408          "LIST FILE INSTRUMENTS <file>" and
409          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
410          about an arbitrary instrument file on the system where the sampler is
411          running on

413    Version 0.5.0 (15 October 2007)
414    
415      * packaging changes:
416        - config.h is not going to be installed along with liblinuxsampler's
417          API header files anymore
418      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
419        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
420        - added completely new XCode project files for Mac OSX which is now
421          capable to execute our autoconf environment, thus no need anymore
422          to maintain the compile time configuration file (osx/version.h) for
423          OSX manually (patch by Toshi Nagata)
424        - fixed buggy boolean --enable-foo / --disable-foo configure script
425          parameters
426        - global.h now only covers global definitions that are needed for the
427          C++ API header files, all implementation internal global definitions
428          are now in global_private.h
429        - atomic.h is not exposed to the C++ API anymore
430        - no need to include config.h anymore for using LS's API header files
431        - fixed warnings in API doc generation

460        - Implemented new, improved notification system
461        - fixed compilation errors regarding OSX
462          (patch by Toshi Nagata)
463        - implemented instruments database
464        - added support for escape sequences to the instruments database
465        - added highly experimental support for on-the-fly instrument editing
466          within the sampler's process (by using instrument editor plugins),
467          you'll notice the new "Registered instrument editors:" message on
468          startup, added a new LSCP command:
469          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
470          to spawn a matching instrument editor for the instrument on the
471          given sampler channel, the plugin path can be overridden at compile
472          time with ./configure --enable-plugin-dir=/some/dir
473        - added experimental code for synchronizing instrument editors hosted
474          in the sampler's process to safely edit instruments while playing
475          without a crash (hopefully) by either suspending single regions
476          wherever possible or if unavoidable whole engine(s)
477        - fixed several issues in fundamental "Thread" class: set scheduling
478          policy and priority on thread level, set a minimum stack size for
479          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
480          threads simply inherited properties of starting thread instead of
481          setting their own policy and priority
482        - minor fix in our automatic stack trace mechanism on crashes, the
483          main process did not wait for the stack trace process to finish
484          its output
485        - fixed some minor memory leaks
486        - reenabled assembly features support, at the moment only for
487          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
488        - minor assembly fix in x86 features detection (don't use the PIC
489          register, to avoid relocations in the text segment at runtime)
490        - POSIX callback functions of Thread.h are hidden
491

515        - minor fix of EGDecay (patch by Toshi Nagata)
516        - fixed compiler error when --enable-override-filter-type was
517          supplied to the configure script (fixes #46)
518        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
519          instead of a fix value
520        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
521          127 (solo mode) only kill voices if the respective mode really
522          changed
523    
524      * LSCP server:
525        - fixed compile time error for old Bison versions
526          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
527        - parser now supports extended ASCII character set
528          (up to ASCII code 255, i.e. includes now umlauts and accents)
529        - filename arguments in LSCP commands now allow to use escape
530          sequences, that is directly literal as one of: \', \", \\, \n, \r,
531          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
532          code value like \xf2) (fixes bug #24)
533        - the following LSCP commands now also support escape sequences for at
534          least one of their text-based parameters (i.e. name, description):
535          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
536          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
537          "SET DB_INSTRUMENT_DIRECTORY NAME",
538          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
539          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
540          "FIND DB_INSTRUMENT_DIRECTORIES"
541        - returns verbose syntax errors (line and column where syntax error
542          occured, the unexpected character and the actually expected, possible
543          character(s), the latter only if less than 5 possibilities)
544        - made sure that LSCP syntax is not affected by gigedit locale
545          settings
546        - bugfix regarding strings parameter lists: all comma separated lists
547          of strings were treated as being one string containing commas
548          (fixes #57)
549

551      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
552      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
553        channel audio output device"        channel audio output device"
554        - fixed a crash which occurs when reassigning the same engine
555          on a sampler channel with connected MIDI device
556        - fixed a crash which occurs when changing the number of ports of a MIDI
557          device connected to a sampler channel to number less then or equal
558          to the index of the port to which the sampler channel is connected.
559        - The previous bindings were not been disconnected when altering
560          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
561          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
562        - The active stream/voice count statistic was incorrect.
563        - notification events were not been sent for some sampler
564          channel changes
565        - added default min and max values to restrict the number of allowed
566          audio output channels and MIDI input ports
567        - the connection to the PCM interface is now closed when destroying
568          an audio output device
569        - files with slash in their path or filename could not be loaded
570
